Bits 7 to 0: Receive Channel Idle Code Insertion Control Bits for Channels 1 to 32 (CH[1:32]).
0 = no clock is present on RCHCLK during this channel time
1 = force a clock on RCHCLK during this channel time. The clock will be synchronous with RCLK if the
elastic store is disabled, and synchronous with RSYSCLK if the elastic store is enabled.
When 2.048MHz backplane mode is selected, this register allows the user to enable the gapped clock on
RCHCLK for any of the 32 possible backplane channels.
When 1.544MHz backplane mode is selected, the LSB of this register determines whether or not a clock is
generated on RCHCLK during the F-bit time:
In this mode, RGCCS4.1:RGCCS4.7 should be set to 0.
0 = do not insert data from the Idle Code Array into the receive data stream
1 = insert data from the Idle Code Array into the receive data stream
